Question

In Scala how do I build up a URL with query string parameters programmatically?

Also how can I parse a String containing a URL with query string parameters into a structure that allows me to edit the query string parameters programmatically?

The following library can help you parse and build URLs with query string parameters (Disclaimer: This is my own library): https://github.com/lemonlabsuk/scala-uri

It provides a DSL for building URLs with query strings:

val uri = "http://example.com" ? ("one" -> 1) & ("two" -> 2)

You can parse a uri and get the parameters into a Map[String,List[String]] like so:

val uri = parseUri("http://example.com?one=1&two=2").query.params
